Key takeaway: Cashing out from prediction markets generally requires converting your holdings to USDC (or USD), moving funds to your own wallet or bank account, and then exchanging to your home currency. Depending on your chosen platform and withdrawal method, this can take anywhere from 5 minutes up to 3 business days.
Understanding how to withdraw from prediction markets matters as much as learning how to fund your account. Many beginners concentrate on purchasing shares but encounter unexpected complexity when they attempt to realise their earnings. This article walks through the process across all leading platforms.
Withdrawing from Polymarket
- Liquidate your position — offload your shares via the order book (alternatively, hold until market settlement for the complete payout)
- Go to Portfolio → Withdraw
- Choose your withdrawal network — Polygon (minimal cost, nearly instant) or Ethereum (steeper gas costs, 5-15 minutes)
- Provide your wallet address — verify carefully; once sent on the blockchain, transactions cannot be reversed
- Authorise the withdrawal — your USDC will land in your external wallet between 1-10 minutes via Polygon
- Exchange to fiat currency — transfer USDC to Coinbase, Kraken, or Binance and exchange for EUR/USD/GBP, then withdraw to your bank account
Withdrawing from Kalshi
Kalshi operates via conventional banking infrastructure because it holds CFTC registration as an exchange:
- Go to Account → Withdraw
- Choose your connected bank account (ACH) or electronic wire
- Specify the amount and verify
- Money reaches your account within 1-3 business days (ACH) or the same business day (wire, $25 charge)
Common Withdrawal Issues
| Issue | Cause | Solution |
| Withdrawal pending for hours | Blockchain congestion or regulatory screening | Allow 24 hours to pass, then reach out to customer support |
| Wrong network selected | Transferred USDC via Polygon to an address that only accepts Ethereum | Recovery is possible if you own the corresponding private key |
| KYC re-verification | Substantial withdrawal initiates a regulatory verification process | Provide requested paperwork without delay |
| Minimum withdrawal not met | Platform enforces a minimum withdrawal size | Add funds to your account to reach the required floor |
Withdrawal Fees by Platform
| Platform | Method | Fee | Speed |
| Polymarket | Polygon USDC | < $0.01 | 1-5 min |
| Kalshi | ACH | Free | 1-3 days |
| Kalshi | Wire | $25 | Same day |
| PolyGram | Polygon USDC | Free | 1-10 min |
Tax Implications of Withdrawals
The act of withdrawing money itself does not create a taxable event — however, selling your shares (closing your position) does. Consult our prediction market tax guide for comprehensive information on filing obligations across the United States, European Union, and United Kingdom.
